Referring to fig. 1, fig. 1 shows the main process of the automatic control method for the anti-fog mirror provided by the present invention, specifically, the method comprises the following six steps:
step one, turning on an anti-fog mirror and operating in a low-power state when detecting that the air humidity reaches a first threshold value;
step two, the photosensitive sensor records the light transmittance of the mirror surface as a first transmittance while the anti-fog film is opened;
step three, detecting the light transmittance of the mirror surface in real time by a photosensitive sensor, and controlling the anti-fog mirror to be switched to a high-power state to operate when detecting that the second transmittance is lower than the first transmittance and the difference value between the second transmittance and the first transmittance reaches a second threshold value;
step four, the photosensitive sensor detects the light transmittance degree of the mirror surface in real time, and controls the anti-fog mirror to be switched to a low-power state to operate when detecting that the third transmittance is higher than the second transmittance and the difference value between the third transmittance and the second transmittance reaches a third threshold value;
step five, detecting the light transmittance degree of the mirror surface in real time by a photosensitive sensor, and controlling the anti-fog mirror to be switched to a high-power state to operate or to be kept in a low-power state to operate according to the comparison relation between the light transmittance degree of the mirror surface and the first transmittance or the second transmittance;
and step six, controlling the anti-fog mirror to be closed when the air humidity is detected to be lower than the first threshold value.
Specifically, a photosensitive sensor is arranged on the back of the mirror surface of the anti-fog mirror, and the setting mode is as follows: the method comprises the steps of selecting a position for mounting a photosensitive sensor on a lens of the anti-fog mirror, removing a back plating layer of the lens at the position, and fixedly mounting the photosensitive sensor at the position so that a detection surface of the photosensitive sensor faces the outside of the lens.
The back of the lens of the antifogging mirror is provided with a heating film which heats the lens so as to eliminate water mist on the mirror surface.
In this embodiment, a humidity sensor is further disposed on the anti-fog mirror for detecting air humidity. The first threshold is set to be 80% relative humidity, and when the humidity sensor detects that the humidity of the air reaches 80%, the controller of the heating film controls the heating film to be turned on, and controls the heating film to operate in a low power state, where the specific value of the low power is 10W in this embodiment. When the heating film is operated in a low-power state, the generation of water mist on the mirror surface can be delayed, but the water mist with higher coverage degree can still be generated on the mirror surface along with the time.
When the heating film of antifog mirror was opened, the mirror surface printing opacity degree of photosensitive sensor record this moment was first transmittance, and the cover degree that water smoke or water smoke have not appeared on the mirror surface this moment is extremely low, does not influence user's observation, consequently uses first transmittance as the follow-up benchmark of judging antifog mirror printing opacity degree change, can avoid the problem that the light source luminance discordance under the different service environment leads to mirror surface printing opacity degree change to judge inefficacy.
In the operation process of the heating film of the anti-fog mirror, the photosensitive sensor also detects the light transmission degree of the mirror surface in real time.
Along with the rising of ambient humidity, the water smoke coverage degree on the mirror surface of antifogging mirror also risees, the mirror surface light transmittance degree that corresponding photosensitive sensor detected also is reducing, when photosensitive sensor detected a second transmittance and satisfies that this second transmittance is less than first transmittance and reach the condition of second threshold value with the difference of first transmittance, can judge this moment and draw the water smoke coverage degree on the mirror surface higher, the user can't carry out clear observation already, consequently can switch the heating film to high power state operation under this condition, operating power through improving the heating film, improve the temperature of heating film and mirror surface, in order to clear away the water smoke on the mirror surface fast. In the present embodiment, the second threshold value is set to 60lx, and the heating film operation power in the high power operation state is 30W.
After the heating film operates with the high power for a period of time, the water smoke on the mirror surface is clear away, the mirror surface light transmittance degree that the sensor detected of closing the door this moment resumes to higher level again, when photosensitive sensor detected a third transmittance and satisfied this third transmittance be higher than the second transmittance and reach the condition of third threshold value with the difference of second transmittance, can judge this moment and draw the water smoke coverage degree on the mirror surface lower, the user can carry out comparatively clear observation, consequently can switch the heating film to the low power state operation under this condition, operating power through reducing the heating film, reduce the consumption of heating film, can delay the water smoke on the mirror surface to regenerate simultaneously again. In the present embodiment, the third threshold value is set to 30 lx.
After the heating film is switched from low power to high power and then switched to low power when starting, if the air humidity in the environment still keeps a higher level, the water mist on the mirror surface can be accumulated again along with the time so that the water mist coverage degree reaches a higher level, at the moment, when the photosensitive sensor detects that the transmittance of the mirror surface meets the condition of second transmittance, the heating film can be switched to the high power state again for operation, and after the water mist is removed, the heating film can be switched to the low power state for operation again. If the air humidity in the environment is reduced before being compared, the water mist on the mirror surface cannot reach the condition that the transmittance of the mirror surface meets the second transmittance, and the heating film always keeps running in a low-power state.
When the humidity sensor detects that the humidity of the air is lower than a first threshold value, the heating film can be controlled to be closed.
According to the automatic control method for the anti-fog mirror, the change of the light transmission degree of the anti-fog mirror, which is detected by the photosensitive sensor arranged on the back of the surface of the anti-fog mirror, is used for judging the water mist coverage degree of the surface of the anti-fog mirror and controlling the anti-fog mirror to operate in a low-power or high-power state according to the water mist coverage degree, so that the anti-fog mirror operates in the high-power state only when necessary, and the use power consumption of the anti-fog mirror is reduced.
The description of the above specification and examples is intended to be illustrative, but not limiting, of the scope of the invention. Modifications, equivalents and other improvements which may occur to those skilled in the art and which may be made to the embodiments of the invention or portions thereof through a reasonable analysis, inference or limited experimentation, in light of the common general knowledge, the common general knowledge in the art and/or the prior art, are intended to be within the scope of the invention.
